looking for a family member

I'm trying to research my husbands biological family. His birth name was Ronald Abbott, born on June 16, 1952 at Vancouver General Hospital or rather in a cab outside the hospital. His birth mother was a Abbott possibly from Montreal,Quebec. I believe her family may be in the hair salon business. Ron's adoptive mother was Joan Hagstead, she later married a Thurston and then a Robertson.I also think Ron's biological mom was a teenager when she gave birth to him. If anybody has any infomation pertaining to this, please let me know. Thanks.
